DSLR vs. webcam imaging the whole Moon
I had this dilemma: what to use to image the whole disk of the Sun or the Moon? Make full disk pictures with my DSLR – 60 frames tops – or record many little videos with my webcam and put the mosaic pieces together? On one hand it is how much time I am willing to invest and on the other, what output quality I am expecting.
The tech
SCOPE: I used my 150/750 on the motorized EQ3.
DSLR: it is a Canon 1100D (also known as the EOS Rebel T3), unmodified hardware but enhanced by Magic Lantern (thanks guys :) ). The sensor is a 12.20 Megapixels CMOS APS-C (pixel size = 5.2 μm), capable of outputting 14 bits deep raw (cr2).
WEBCAM: it is a Scopium webcam, 640×480 pixels 8 bits sensor, max framerate is 30 fps, video is recorded in raw mode (pixel size = 5.6 μm). (tovább…)
